Description

Technical Field

[0001] This utility model relates to the technical field of tobacco processing equipment, and in particular to a belt cleaning device for tobacco. Background Technology

[0002] Belt conveyors are commonly used material handling equipment in tobacco processing. However, over long-term use, tobacco leaf debris, dust, and other impurities easily accumulate on the surface of the belts. If these impurities are not cleaned in time, they can cause the belts to slip, wear down more quickly, and even affect the normal operation of the production line. Traditional cleaning methods usually rely on manual cleaning, which is inefficient and unsafe.

[0003] Therefore, the prior art provides a tobacco cleaning mechanism on a belt that can solve the above problems:

[0004] Publication No. CN219488703U discloses a tobacco cleaning mechanism on a conveyor belt, which uses two symmetrically arranged shovels that are close to the surface of the belt to remove impurities on the conveyor belt in an oscillating manner. However, in this prior art, if the shovel breaks and needs to be replaced, all the parts connected to the shovel must be disassembled and reassembled, and multiple adjustments must be made before it can be used again, which increases the difficulty and time of disassembly. Utility Model Content

[0005] In view of this, the present invention provides a belt cleaning device for cigarettes, which can solve the technical problem of difficulty in disassembling the cleaning mechanism during replacement in the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] A cigarette belt cleaning device includes a belt mechanism and a cleaning mechanism connected thereto. The belt mechanism includes a drive roller and a transmission roller I located beside and coaxially connected to the drive roller. The drive roller is driven by a driven roller via belt I. The cleaning mechanism includes a cleaning roller brush assembly and roller brush supports symmetrically arranged at its ends. The cleaning roller brush assembly includes cleaning roller brushes and transmission rollers II located beside and coaxially connected to the cleaning roller brushes. Transmission rollers I and II are connected via belt II. A limit bracket is provided above the roller brush supports. A collection mechanism is provided below the cleaning mechanism. The collection mechanism includes a collection channel with a funnel-shaped top. A collection box is provided below the collection channel. The interior of the collection box is divided into a collection area and a debris collection area by a baffle. A filter screen is inclinedly provided at the top of the debris collection area.

[0008] As an improvement to the above technical solution, the cleaning roller brush in the cleaning mechanism is located below belt I in the belt mechanism, and the cleaning roller brush can contact the surface of belt I.

[0009] As an improvement to the above technical solution, the cleaning roller brush is made of wear-resistant material.

[0010] As an improvement to the above technical solution, one end of the roller brush bracket is connected to a fixed plane via a rod shaft, and the other end of the roller brush bracket is connected to the axis position on the end side of the cleaning roller brush assembly.

[0011] As an improvement to the above technical solution, the limiting bracket is inclinedly positioned above the roller brush bracket, pushing the cleaning roller brush until the upper end of the roller brush bracket contacts the bottom end of the limiting bracket.

[0012] As an improvement to the above technical solution, the bottom of the collection channel is directly opposite the top of the collection area of ​​the collection box, and the filter screen set at the top of the collection area is located between the bottom of the collection channel and the top of the collection area of ​​the collection box at a 45-degree angle to the horizontal plane.

[0013] As an improvement to the above technical solution, both the collection channel and the collection box are made of stainless steel.

[0014] Compared with the prior art, the technical solution of this utility model has the following advantages:

[0015] This utility model features a reasonable design structure, high degree of automation, easy installation, easy maintenance, high cleaning efficiency, and low manufacturing cost. The roller brush bracket in this utility model not only provides support for the cleaning roller brush but also adjusts the position of the cleaning roller brush relative to belt I. This allows the cleaning roller brush to be close to belt I, causing belt II to be taut for stable cleaning of belt I, and to be far away from belt I, causing belt II to be slack for easy disassembly and replacement of the cleaning roller brush. The cooperation between the roller brush bracket and the limiting bracket ensures that the cleaning roller brush is within a reasonable contact range with belt I, so that belt II connecting transmission roller I and transmission roller II is just taut. This avoids the cleaning roller brush from excessively contacting belt II or not reaching the appropriate position, causing belt II to slack and resulting in an unstable cleaning effect.

[0016] Other beneficial effects of this invention will be further explained in the following specific embodiments. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] like Figure 1 As shown, this utility model provides a belt cleaning device for cigarettes.

[0024] It includes a belt mechanism and a sweeping mechanism connected to it. The belt mechanism includes a drive roller 2 and a transmission roller I3 located beside the drive roller 2 and coaxially connected to the drive roller 2. The drive roller 2 is driven by a driven roller via belt I1. The sweeping mechanism includes a sweeping roller brush assembly and roller brush supports 7 symmetrically arranged at its ends. The sweeping roller brush assembly includes a sweeping roller brush 6 and a transmission roller II5 located beside the sweeping roller brush 6 and coaxially connected to the sweeping roller brush 6. The transmission roller I3 and the transmission roller II5 are connected by belt II4. A limit bracket 8 is provided above the roller brush support 7. A collection mechanism is provided below the sweeping mechanism. The collection mechanism includes a collection channel 9 with a funnel-shaped top. A collection box 11 is provided below the collection channel 9. The inside of the collection box 11 is divided into a collection area 1101 and a debris collection area 1102 by a baffle. A filter screen 10 is inclinedly provided at the top of the debris collection area 1102.

[0025] In the embodiments described in this utility model, the belt mechanism is powered by a motor connected to the drive roller 2, which in turn drives the sweeping mechanism via belt II 4. This achieves the goal of meeting the sweeping mechanism's sweeping requirements without requiring additional power support, thus saving energy and reducing maintenance costs. Under the action of the motor connected to the drive roller 2, the drive roller 2 can drive the transmission roller I 3 located beside it and coaxially connected to it to rotate in the same direction as the drive roller 2, which in turn drives the sweeping mechanism via belt II 4 connected to the transmission roller I 3.

[0026] In the embodiments described in this utility model, the cleaning mechanism has the function of cleaning materials and impurities adhering to the surface of belt I1 in the belt mechanism. The cleaning roller brush 6 in the cleaning mechanism is located below belt I1 in the belt mechanism, and the cleaning roller brush 6 can contact the surface of belt I1. When belt II4 connected to transmission roller I3 in the belt mechanism drives transmission roller II5 in the cleaning mechanism to rotate in the same direction as transmission roller I3, transmission roller II5 can drive the cleaning roller brush 6 coaxially connected to it to rotate in the same direction. At this time, the movement direction of cleaning roller brush 6 is opposite to the running direction of belt I1, so as to improve the cleaning effect of removing materials and impurities adhering to the surface of belt I1 by continuous rotational contact between cleaning roller brush 6 and the surface of belt I1.

[0027] In the embodiments described in this utility model, the cleaning roller brush 6 is made of wear-resistant material, which gives the cleaning roller brush 6 a strong cleaning ability.

[0028] In the embodiments described in this utility model, the roller brush bracket 7 not only provides support for the cleaning roller brush 6, but also adjusts the position of the cleaning roller brush 6 relative to the belt I1, allowing the cleaning roller brush 6 to move closer to the belt I1, causing the belt II4 to be tensioned and thus stably cleaning the surface of the belt I1; and to move away from the belt I1, causing the belt II4 to be loosened, facilitating the disassembly and replacement of the cleaning roller brush 6. One end of the roller brush bracket 7 is connected to a fixed plane via a rod shaft 12. The other end of the frame 7 is connected to the axis on the end side of the cleaning roller brush assembly. Under the action of the roller brush support 7, when the cleaning roller brush 6 is pushed to move upward around the rod shaft 12 until it contacts the surface of the belt I1, the belt II4 connecting the transmission roller I3 and the transmission roller II5 will be in a taut state. At this time, the cleaning roller brush 6 reaches a steady state under the action of three vector forces: its own weight, the tension of the belt II4, and the supporting force of the roller brush support 7. Then, the cleaning roller brush 6 can be driven to start cleaning the material and impurities adhering to the surface of the belt I1.

[0029] It should be noted that the calculation method for the length L of belt II4 is as follows:

[0030] L=πr1+πr2+2*l1l2

[0031] Where r1 is the circumferential radius of transmission roller II5, r2 is the circumferential radius of transmission roller I3, and l1 and l2 are the center-to-center distances between transmission roller II5 and transmission roller I3.

[0032] When the sweeping roller brush 6 is pulled down so that it moves downward around the shaft 12 and away from the belt I1, the belt II4 connecting the transmission roller I3 and the transmission roller II5 will be in a slack state. At this time, the steady state of the sweeping roller brush 6 is broken, and the sweeping roller brush 6 is in a natural drooping state under the action of the roller brush bracket 7, so as to facilitate the disassembly, replacement and cleaning of the sweeping roller brush 6.

[0033] In the embodiments described in this utility model, the limiting bracket 8 has the function of limiting the position of the cleaning roller brush 6 driven by the roller brush bracket 7 to approach the belt I1, so that the cleaning roller brush 6 can be in a reasonable range of contact with the belt I1, that is, one-third to two-thirds of the bristles of the cleaning roller brush 6 can contact the surface of the belt I1. The limiting bracket 8 is inclinedly arranged above the roller brush bracket 7, pushing the cleaning roller brush 6 until the upper end surface of the roller brush bracket 7 contacts the bottom end of the limiting bracket 8, so that the belt II4 connecting the transmission roller I3 and the transmission roller II5 is just in a taut state, avoiding the cleaning roller brush 6 from excessively contacting the belt II4 or not reaching the appropriate position, causing the belt II4 to loosen and failing to achieve a stable cleaning effect.

[0034] In the embodiments described in this utility model, the collecting mechanism has the function of collecting materials and impurities adhering to the surface of the belt I1 cleaned by the cleaning mechanism, and screening them according to the particle size of the materials and the year-end. The collecting channel 9 is located directly below the cleaning roller brush 6. The funnel-shaped design at the top of the collecting channel 9 ensures that all materials and impurities adhering to the surface of the belt I1 cleaned by the cleaning roller brush 6 can enter the collecting channel 9. The bottom of the collecting channel 9 is directly opposite the top of the impurity collection area 1102 of the collecting box 11. The filter screen 10 set at the top of the impurity collection area 1102 is at an angle of 4° to the horizontal plane. The 5-degree incline is located between the bottom of the collection channel 9 and the top of the collection area 1102 of the collection box 11. Materials and impurities falling from the top of the collection channel 9 to the bottom of the collection channel 9 are transported to the collection area 1101 of the collection box 11 along with the inclined filter screen 10 for residual smoke treatment. Impurities smaller than the filter screen 10 fall into the collection area 1102 of the collection box 11 through the filter holes on the surface of the filter screen 10 for centralized removal. This not only improves the utilization rate of materials but also facilitates the removal of impurities, thereby improving the purity of the materials.

[0035] In the embodiments described in this utility model, the mesh size of the filter screen 10 can be selected according to the size of the impurities to be filtered as needed.

[0036] In the embodiments described in this utility model, both the collection channel 9 and the collection box 11 are made of stainless steel.

[0037] Based on the above, the working steps of this utility model are as follows:

[0038] Step S1: First, adjust the tilt position of the limiting bracket 8 so that when the upper end of the brush 6 is pushed until the upper end of the brush bracket 7 contacts the bottom end of the limiting bracket 8, the belt II4 connecting the transmission roller I3 and the transmission roller II5 is just taut, and the brush 6 is in a reasonable range of contact with the belt I1. At this time, the belt II4 is not yet assembled to the transmission roller I3 and the transmission roller II5, and the brush 6 is in a natural drooping state under the action of the brush bracket 7.

[0039] Step S2: Assemble belt II4 onto the surfaces of drive rollers I3 and II5, and push the cleaning brush 6 upwards so that it moves upwards around the shaft 12 until the upper end of the brush bracket 7 contacts the bottom end of the limiting bracket 8, so that belt II4 connecting drive rollers I3 and II5 is just taut. The cleaning brush 6 contacts belt I1, and at this time, the cleaning brush 6 reaches a steady state under the action of three vector forces: its own weight, the tension of belt II4, and the supporting force of brush bracket 7. Then start the motor connected to the drive roller 2 to actively... Roller 2 can drive transmission roller I3, which is located beside it and coaxially connected to it, to rotate in the same direction as drive roller 2. Then, through belt II4 connected to transmission roller I3, it drives transmission roller II5 in the sweeping mechanism to rotate in the same direction as transmission roller I3. Transmission roller II5 can drive sweeping brush 6, which is coaxially connected to it, to rotate in the same direction. At this time, the movement direction of sweeping brush 6 is opposite to the running direction of belt I1, so as to improve the sweeping effect of removing materials and impurities adhering to the surface of belt I1 by continuous rotational contact between sweeping brush 6 and the surface of belt I1.

[0040] Step S3: The cleaning roller brush 6 sweeps the material and impurities adhering to the surface of the belt I1 and drops them from the top of the collection channel 9 to the filter screen 10 at the bottom of the collection channel 9. Material larger than the mesh size of the filter screen 10 can be transported to the collection area 1101 of the collection box 11 for residual smoke treatment, while impurities smaller than the mesh size of the filter screen 10 fall into the collection area 1102 of the collection box 11 for centralized cleaning.

[0041] Step S4: After the process of cleaning the material and impurities adhering to the surface of belt I1 is completed, when it is necessary to clean and replace the cleaning roller brush 6, pull down the cleaning roller brush 6 so that it moves downward around the rod shaft 12 to move away from belt I1. The belt II4 connecting the transmission roller I3 and the transmission roller II5 will be in a slack state. At this time, the steady state of the cleaning roller brush 6 is broken. The cleaning roller brush 6 is in a natural drooping state under the action of the roller brush bracket 7. Then, remove belt II4 and cleaning roller brush 6 in sequence to complete the disassembly operation of cleaning roller brush 6.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
