Description

Technical Field

[0001] This invention relates to the field of tobacco production technology, and in particular to a material cleaning device. Background Technology

[0002] In the tobacco processing industry, the feeder is one of the main material conveying devices on the cigarette manufacturing line. It stores a certain amount of tobacco material in different processing steps, acting as a buffer and regulator between processes, and controlling the flow rate of the tobacco material. However, during the use of the feeder, material leakage can occur from the rear elevator belt, causing material to easily scatter on the ground and resulting in waste. Currently, a dust collection box is installed below the rear elevator belt to collect the fallen material. When a large amount of material accumulates in the dust collection box during production, it needs to be manually cleaned. Workers pull the dust collection box out from under the feeder and then clean it with brooms or other cleaning tools. When a large amount of material accumulates in the ash collection box, the box and the material inside are quite heavy, requiring significant physical effort for workers to handle. Furthermore, pulling the box out from under the feeder can cause it to shake, spilling material and breaking tobacco, resulting in waste. Traditional cleaning tools often fail to thoroughly clean the ash collection box and the floor, leading to the breeding of tobacco insects and causing quality issues that affect the process. Additionally, workers need to clean the tailings from each batch, resulting in frequent cleaning and significant physical exertion, impacting both work and production efficiency. Summary of the Invention

[0003] In view of the problems existing in the prior art, the present invention provides a material cleaning device, which is installed in the ash receiving box of the feeder. By using mechanical automation, the ash receiving box is automatically cleaned, which improves the problems of material waste caused by tobacco spillage when the ash receiving box is pulled out during manual cleaning, incomplete cleaning, and labor consumption. At the same time, it effectively eliminates the breeding of tobacco insects due to inadequate cleaning. By using machinery to replace manual labor, it saves labor costs and improves production efficiency.

[0004] The technical solution to the problem solved by the present invention is to provide a material cleaning device for cleaning materials that fall into a dust collection box. The device of this application includes a driving unit, a cleaning unit, and sliding rods. The driving unit is installed on the rear plate of the dust collection box. Sliding rods are provided on the inner walls of both side plates of the dust collection box. The cleaning unit is horizontally mounted between two parallel sliding rods and is slidably connected to the two sliding rods. The lower end of the cleaning unit is in contact with the inner wall of the bottom plate of the dust collection box. The output end of the driving unit is connected to the cleaning unit for transmission. The driving unit drives the cleaning unit to reciprocate along the direction of the sliding rods in the dust collection box, pushing the material out from the front port of the dust collection box.

[0005] Preferably, the front panel of the ash receiving box is equipped with an openable baffle. When the material is pushed to the baffle, the material can push the baffle open, so that the material is swept out of the ash receiving box.

[0006] Furthermore, the drive unit includes a power assembly and a rotating rod. The power assembly is installed on the rear plate of the ash receiving box. One end of the rotating rod is connected to the power assembly for transmission, and the other end is rotatably connected to the front plate of the ash receiving box. The rotating rod is arranged parallel to the sliding rod, and the rotating rod is the output end of the drive unit.

[0007] Optionally, the power component can be a drive motor or a stepper motor, as long as it can make the rotating rod rotate.

[0008] Preferably, the power component can be a drive motor, which specifically includes a fixed base and a rotating output end. The fixed base of the power component is installed on the inner wall of the rear plate of the ash receiving box, and the rotating output end of the power component is connected to the rotating rod for transmission.

[0009] Furthermore, the cleaning unit includes a cleaning plate and a mounting plate. The upper two ends of the cleaning plate are concave, and the depth of the concavity is determined according to the width of the sliding rod. The cleaning plate and the mounting plate are stacked in parallel. The mounting plate is fastened above the sliding rod, and the concave part of the cleaning plate is fastened below the sliding rod, so that the two ends of the cleaning unit form sliding grooves and are slidably connected to the two parallel sliding rods.

[0010] Optionally, the cleaning board and mounting board can be made of hard board materials such as wood, metal, or plastic, as long as they can move materials.

[0011] Preferably, the lower end of the cleaning plate is provided with a stiff, fine-bristled brush to remove fine tobacco shreds accumulated at the bottom of the ash collection box.

[0012] Alternatively, the brush can be made of plastic filaments, natural fibers, etc.

[0013] Furthermore, the outer circumferential surface of the rotating rod is threaded, the cleaning plate is provided with a vertically elongated sliding hole, the mounting plate is provided with a downward-opening mounting groove corresponding to the position of the sliding hole, the groove depth of the mounting groove is not less than the length of the sliding hole, and a limit nut is provided in the sliding hole and the mounting groove, and the rotating rod is screwed to the limit nut.

[0014] Furthermore, the limiting nut includes a first abutment ring, a second abutment ring, and a stud. The stud has a first abutment ring and a second abutment ring at both ends. The stud is located in the sliding hole and the mounting groove. The first abutment ring abuts against the outer wall of the cleaning plate, and the second abutment ring abuts against the outer wall of the mounting plate. The outer diameter of the first abutment ring and the outer diameter of the second abutment ring are larger than the width of the sliding hole.

[0015] Furthermore, the stud has two parallel aligning limiting surfaces on both sides. These limiting surfaces slide against the inner wall of the sliding hole and the inner wall of the mounting groove, allowing the limiting nut to slide up and down within the sliding hole and the mounting groove.

[0016] Furthermore, the power unit can drive the rotating rod to rotate counterclockwise or clockwise. When the rotating rod rotates, it generates sliding friction with the limit nut, which allows the cleaning part to reciprocate within the dust collection box along the direction of the sliding rod.

[0017] Furthermore, the two side plates of the ash receiving box are provided with vertically elongated adjustment holes and a power device. The sliding rod and the power device are connected through the adjustment holes, so that the sliding rod can slide up and down along the adjustment holes to simultaneously adjust the height of the two parallel sliding rods.

[0018] Optionally, the adjustment holes and power units can be installed in one or more sets on one side of the ash receiving box.

[0019] In one implementation, a set of adjustment holes and a power device are respectively provided on the two side plates of the ash receiving box. The two sets of adjustment holes and the power device should be symmetrically arranged on the two side walls of the ash receiving box with the rotating rod as the axis of symmetry, and located at the midpoint of the sliding rod.

[0020] In another implementation, the two side plates of the ash receiving box are provided with two sets of adjustment holes and power devices respectively. The two sets of power devices and sliding holes on the same side plate are respectively located at both ends of the sliding rod. The four sets of power components are symmetrically arranged with the rotating rod as the axis of symmetry.

[0021] Optionally, the power unit can be a drive motor or a stepper motor, which can drive the sliding rod to slide up and down within the adjustment hole.

[0022] Preferably, the power unit is a stepper motor, which can be divided into a fixed base and an output end. The fixed base of the power unit is installed on the outer wall of the side plate of the ash receiving box, and the output end of the power unit passes through the adjustment hole and is connected to the sliding rod, so that the sliding rod can slide up and down along the adjustment hole.

[0023] Optionally, the adjustable range of the adjustment hole can be adjusted to allow the lower end of the cleaning section to be separated from the bottom of the dust collection box.

[0024] Furthermore, when the cleaning section moves backward along the sliding rod to reset, the power unit drives the two parallel sliding rods to simultaneously lift the cleaning section, causing the lower end of the cleaning section to separate from the ash collection box.

[0025] Preferably, when the cleaning section is driven back to the rear plate of the ash receiving box, the lower end of the cleaning section does not fit with the bottom of the ash receiving box, and the reset endpoint of the cleaning section is outside the material dropping range, that is, close to the rear plate of the ash receiving box.

[0026] The beneficial effects of this invention are as follows: 1. This invention is a material cleaning device, installed inside a dust collection box, which uses a mechanical and automated method to achieve automatic material cleaning.

[0027] 2. Traditional manual cleaning methods require removing the ash collection box each time. The automatic cleaning device of this invention replaces manual cleaning, eliminating the need to remove the ash collection box and effectively reducing material waste caused by removing the ash collection box.

[0028] 3. Manual cleaning requires the use of traditional cleaning tools. Using the automatic cleaning device of this invention to replace traditional cleaning tools can clean more thoroughly without consuming physical labor.

[0029] 4. This invention utilizes machinery to replace manual labor, achieving automatic cleaning, reducing labor costs, and improving production efficiency. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] To address the aforementioned problems, this invention proposes a material cleaning device for use in tobacco production lines. It aims to solve the issues of material waste, incomplete cleaning, and unstable work efficiency that arise from manual cleaning of ash collection boxes in the current stage. This invention can be installed inside the ash collection box of an existing feeder to achieve automatic cleaning of the material in the ash collection box.

[0035] Please refer to the specific embodiments of this application. Figure 1-10 : A material cleaning device includes a drive unit 1, a cleaning unit 2, and sliding rods 3. The drive unit 1 is installed on the rear plate of the ash receiving box. Sliding rods 3 are provided on the inner walls of both side plates of the ash receiving box. The cleaning unit 2 is horizontally mounted between the two parallel sliding rods 3 and is slidably connected to the two sliding rods 3. The lower end of the cleaning unit 2 is in contact with the inner wall of the bottom plate of the ash receiving box. The output end of the drive unit 1 is connected to the cleaning unit 2 for transmission. The drive unit 1 drives the cleaning unit 2 to reciprocate along the direction of the sliding rods 3 in the ash receiving box, pushing the material out from the front port of the ash receiving box.

[0036] The cleaning device of this application includes a drive unit 1 comprising a power component 11 and a rotating rod 12 with threads on its outer peripheral surface. The power component 11 drives the rotating rod 12 to rotate clockwise or counterclockwise, so that the cleaning part 2, which is connected to the rotating rod 12, can reciprocate along the rotating rod 12, while the two ends of the cleaning part 2 slide on the sliding rod 3.

[0037] When performing the cleaning function, the lower end of the cleaning section 2 is in contact with the inner wall of the bottom plate of the ash receiving box, so that when the cleaning section 2 reciprocates, it can push the material in the ash receiving box forward and drop it from the front port.

[0038] In a preferred embodiment, the lower end of the cleaning unit 2 is provided with a brush that generates a certain degree of elastic contact friction with the inner wall of the bottom plate of the ash receiving box, thereby realizing the cleaning function of the device. The front end of the ash receiving box is provided with an openable baffle. When the material is pushed to the baffle, the material will push the baffle open.

[0039] In one specific embodiment, the power assembly 11 is pre-set to work for a set time. After the set time is reached, the rotation direction of the rotating rod 12 is changed, and the cleaning part 2 performs a reset motion, so that the cleaning part 2 can be driven by the rotating rod 12 to perform reciprocating motion. However, when there is too much material, the resistance of the cleaning part 2 during movement is large, which may cause jamming and affect the forward movement of the cleaning part 2. As a result, before the cleaning part 2 reaches the baffle, the power assembly 11 changes the rotation direction of the rotating rod 12, so that the material cannot be pushed out of the ash collection box.

[0040] In a preferred embodiment, the cleaning device of this application can pre-set the number of rotations of the power component 11, so that when the cleaning part 2 reaches the baffle, the power component 11 can change the rotation direction of the rotating rod 12, thereby controlling the cleaning part 2 to reset.

[0041] It is understood that the power component 11 can be a drive motor or a stepper motor, as long as it can drive the rotating rod 12 to rotate. In a specific embodiment of this application, the power component 11 is a stepper motor, the fixed base of the power component 11 is installed on the inner wall of the rear plate of the ash receiving box, the rotating rod 12 is arranged perpendicularly to the power component 11, and the rotation output end of the power component 11 is connected to one end of the rotating rod 12.

[0042] As a preferred embodiment, the cleaning unit 2 is made of wood, which is low in cost and has sufficient hardness to move the material in the dust collection box.

[0043] As a preferred embodiment, please refer to Figure 3 : The power assembly 11 is installed in the middle of the inner wall of the rear plate of the ash receiving box, and the rotating rod 12 is connected to the rotating output end of the center of the power assembly 11.

[0044] In one specific embodiment, if the sliding rods 3 are not provided on both sides of the ash receiving box, the two ends of the cleaning part 2 will continuously rub against the inner walls of the two side plates of the ash receiving box when it reciprocates. This can easily cause jamming or jamming during the production process. Moreover, if the usage time is too long, it can easily cause severe wear on the inner walls of the two side plates of the ash receiving box and the two ends of the cleaning part 2. Workers need to disassemble, inspect, and replace them regularly, which increases the production process and consumes manpower.

[0045] Based on the problems that may arise in practical applications, please refer to the specific embodiments of this application. Figure 3 : In order to reduce the need for frequent inspection and replacement of the side plates of the ash receiving box and the cleaning part 2, and to reduce the occurrence of jamming or stuckness during the use of this device, a sliding rod 3 is installed on the inner wall of each side plate of the ash receiving box. The two ends of the cleaning part 2 are slidably connected to the sliding rod 3, which makes the reciprocating motion of the cleaning part 2 smoother and reduces the wear of the side plates of the ash receiving box and the cleaning part 2.

[0046] In a preferred embodiment, the two sliding rods 3 should be arranged in parallel so that the cleaning part 2 is horizontally mounted in the ash collection box and always remains horizontal.

[0047] In one specific embodiment, the cleaning part 2 is a whole. Ideally, the two ends of the cleaning part 2 are provided with grooves that are the same thickness and width as the sliding rod 3. After installation, the sliding rod 3 can fit into the groove. However, in reality, errors are easy to occur when designing the groove, which leads to the groove of the cleaning part 2 not matching the sliding rod 3, resulting in the inability to install or the instability when sliding after installation.

[0048] Considering the stability of the cleaning section 2 during the sliding process, in the specific embodiment of this application, the cleaning section 2 is divided into a cleaning plate 21 and a mounting plate 22. Please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 5 and Figure 7 : The upper half of the cleaning plate 21 has concave sliding grooves at both ends. The depth of the concave sliding grooves is determined by the width of the sliding rod 3, so that after the cleaning plate 21 is placed in the dust collection box, the sliding grooves can slide and fit with the sliding rod 3. The width of the mounting plate 22 is narrower than that of the cleaning plate 21. The mounting plate 22 is stacked parallel to the cleaning plate 21 and is located above the sliding rod 3. Its two ends are fitted with the inner walls of the two side plates of the dust collection box, so that the cleaning part 2 can be placed between the two side plates of the dust collection box and slide and fit with the sliding rod 3 of the dust collection box. The cleaning part 2 can maintain stability when sliding.

[0049] As a preferred embodiment, please refer to Figure 4 and Figure 6 : The cleaning plate 21 has a vertically elongated sliding hole 211 in the middle, and the mounting plate 22 has a mounting groove in the middle corresponding to the position of the sliding hole 211. The opening of the mounting groove faces downward, and the groove depth of the mounting groove is not less than the length of the sliding hole 211. A limiting nut 23 is provided in the sliding hole 211 and the mounting groove. The rotating rod 12 passes through the sliding hole 211 and the mounting groove and is screwed to the limiting nut 23. The cleaning plate 21 and the mounting plate 22 abut against each other through the limiting nut 23.

[0050] The limiting nut 23 includes a first abutting ring 231, a second abutting ring 232, and a stud 233. The stud 233 has a thread inside that corresponds to the rotating rod 12. The two ends of the stud 233 are provided with a first abutting ring 231 and a second abutting ring 232. The stud 233 is located in the sliding hole 211 and the mounting groove of the cleaning part 2 and is screwed to the rotating rod 12. The first abutting ring 231 abuts against the outer wall of the cleaning plate 21, and the second abutting ring 232 abuts against the outer wall of the mounting plate 22.

[0051] In one specific embodiment, if the outer diameter of the first abutting ring 231 and the second abutting ring 232 is not greater than the width of the sliding hole 211, the limiting nut 23 will be unable to abut the cleaning plate 21 and the mounting plate 22, and the mounting plate 22 will fall off.

[0052] Based on the overall stability of the cleaning section 2, the outer diameter of the first abutment ring 231 and the outer diameter of the second abutment ring 232 are greater than the width of the sliding hole 211, so as to achieve abutment between the cleaning plate 21 and the mounting plate 22, making the structure of the cleaning section 2 more stable.

[0053] In one specific embodiment, the stud 233 is a cylinder. If the cylindrical surface of the stud 233 is tangent to the inner wall of the sliding hole 211 and the inner wall of the mounting groove, the limiting nut 23 will rotate with the rotating rod 12 when the rotating rod 12 rotates. Since the cylindrical surface of the stud 233 is tangent to the inner wall of the sliding hole 211 and the inner wall of the mounting groove, the sliding friction is small, so the rotating rod 12 cannot drive the cleaning part 2 to reciprocate.

[0054] Based on the situations encountered in practical applications, please refer to the specific embodiments of this application. Figure 9 and Figure 10 : In order to enable the cleaning part 2 to be driven by the rotating rod 12 to perform reciprocating motion, two parallel limiting surfaces 234 are provided on both sides of the stud 233. The limiting surfaces 234 slide against the inner wall of the sliding hole 211 and the inner wall of the mounting groove, so that the limiting nut 23 can be locked in the sliding hole 211 and the mounting groove, increasing the sliding friction, so that the rotating rod 12 can drive the cleaning part 2 to perform reciprocating motion when it rotates.

[0055] In one specific embodiment, the lower end of the cleaning plate 21 is attached to the inner wall of the bottom plate of the ash collection box to scrape off the material in the ash collection box. However, since the cleaning plate 21 is made of hard wood, the bottom surface of the wood is relatively rough, which will damage the tobacco shreds accumulated at the bottom. In addition, the uneven bottom surface will cause small materials in the ash collection box to be unable to be cleaned, resulting in incomplete cleaning.

[0056] Based on the principle that it can protect the tobacco and clean more thoroughly in practical applications, in a specific embodiment of this application, the bottom of the cleaning plate 21 is provided with a brush. The brush is attached to the inner wall of the bottom plate of the ash collection box, so that when the cleaning plate 21 moves back and forth, it can brush away the tobacco accumulated at the bottom of the ash collection box, making the cleaning more thorough and reducing damage to the tobacco.

[0057] As a preferred embodiment, the brush at the bottom of the cleaning plate 21 is a hard, fine brush with a large number of bristles, which can not only push the material out of the ash collection box, but also clean the small material residue at the bottom of the ash collection box.

[0058] In one specific embodiment, when the cleaning unit 2 pushes the material forward, the baffle of the front plate of the ash receiving box is not pushed open because the material accumulation is small, and the material accumulates in the front half of the ash receiving box.

[0059] As a preferred embodiment, the lower half of the cleaning plate 21 is provided with a stop block, so that when the cleaning part 2 moves to the baffle, the stop block can push the baffle open, thereby solving the problem that the baffle cannot be pushed open when there is insufficient material accumulation.

[0060] In one specific embodiment, if the fine brush at the bottom of the cleaning plate 21 brings back the small tobacco shreds that were not completely pushed out during the resetting process, the ash collection box will not be cleaned properly. Long-term uncleanliness will breed tobacco insects, and the tobacco shreds brought back into the ash collection box will not be able to be re-mixed into the feeder, resulting in material waste.

[0061] Based on the situations encountered in practical applications described above, please refer to the specific embodiments of this application. Figure 8 : The height of the sliding rod 3 is adjusted by the power device 42. Each of the two side plates of the ash receiving box has a vertically elongated adjustment hole 41. The sliding rod 3 is connected to the power device 42 through the adjustment hole 41, so that the power device 42 can drive the sliding rod 3 to slide up and down along the adjustment hole 41.

[0062] It is understood that the power device 42 is a stepper motor. The power device 42 can be further divided into a fixed base and an output end. The fixed base of the power device 42 is installed on the outer wall of the side plate of the ash receiving box. The output end of the power device 42 passes through the adjustment hole 41 and is connected to the sliding rod 3, so that the sliding rod 3 can slide up and down along the adjustment hole 41.

[0063] In one specific embodiment, two sets of power devices 42 and two adjustment holes 41, respectively located on the outer walls of the two side plates of the ash collection box, are symmetrical about the rotating rod 12 as the axis of symmetry, and synchronously drive the two parallel sliding rods 3 to slide to the same height position. There is only one set of power devices 42 on the same side plate, which is located at the midpoint of the sliding rod 3. When driving the sliding rod 3 to slide up and down, the sliding rod 3 will be unstable from left to right. Moreover, since the cleaning part 2 itself also has weight, the sliding rod 3 will shake more.

[0064] As a preferred embodiment, please refer to Figure 3 : Each end of the sliding rod 3 is equipped with a power unit 42. The four power units are symmetrically arranged with the rotating rod 12 as the axis of symmetry. The four power units 42 synchronously drive the two parallel sliding rods 3 to slide to the same height position, so that the sliding rods 3 can always maintain a horizontal posture during the up and down sliding process.

[0065] In a preferred embodiment, when the cleaning section 2 is driven back to the rear plate of the ash receiving box, the brush at the lower end of the cleaning section 2 does not contact the bottom inner wall of the ash receiving box, and the cleaning section 2 is outside the material dropping range, that is, close to the rear plate of the ash receiving box.

[0066] In a specific embodiment of this application, when a large amount of material accumulates in the ash receiving box, the material cleaning device of this application is activated. Before activation, the cleaning part 2, which is installed between the two side plates of the ash receiving box, is located at the rear end of the ash receiving box. The two ends of the cleaning part 2 are slidably attached to two parallel sliding rods 3. The brush at the lower end of the cleaning part 2 is elastically attached to the bottom inner wall of the ash receiving box, and the cleaning part 2 is outside the material dropping range, that is, close to the rear plate of the ash receiving box. The limiting nut 23 and the rotating rod 12 are located below the sliding hole 211. At this time, the two sliding rods 3 are located above the adjusting hole 41. Four sets of power units 42, located at both ends of the two sliding rods 3, synchronously drive the sliding rods 3 downward along the adjustment hole 41 to a position below the adjustment hole 41. At this time, the cleaning part 2 moves downward with the sliding rods 3 until the hard, fine brush at the bottom of the cleaning part 2 is in contact with the bottom inner wall of the dust collection box. Then, the power unit 11 drives the rotating rod 12 to rotate clockwise. At this time, the limiting nut 23 has a tendency to rotate as well, but due to the limiting cut surfaces 234 on both sides of the stud 233, the limiting nut 23 is fixed in place within the sliding hole 211 and the mounting groove. Then, through the stud 233... The sliding friction between the sliding hole 211 and the mounting groove drives the cleaning section 2 to move forward along the rotating rod 12. At this time, both ends of the cleaning section 2 slide forward along the sliding rod 3, causing the cleaning section 2 to push the accumulated material. The brush at the lower end of the cleaning section 2 cleans the fine tobacco shreds at the bottom of the ash box. When the power unit 11 rotates to the preset number of revolutions, the cleaning section 2 is at the front port of the ash box, at the baffle. The stop block on the cleaning section 2 can push the baffle open, allowing the material to be pushed out of the baffle by the cleaning section 2. Then, the four sets of power units 42 synchronously drive the two parallel rods. The sliding rod 3 moves upward along the adjustment hole 41 to the position above the adjustment hole 41. At this time, the brush at the lower end of the cleaning part 2 leaves the bottom of the ash receiving box, forming a gap. At the same time, the power unit 11 drives the rotating rod 12 to rotate counterclockwise, so that the cleaning part 2 suspended above the bottom plate of the ash receiving box is driven back to the rear end of the ash receiving box. Finally, the four sets of power units 42 synchronously drive the two parallel sliding rods 3 to move downward along the adjustment hole 41 to the position below the adjustment hole 41. At this time, the brush at the lower end of the cleaning part 2 elastically re-adheres to the bottom inner wall of the ash receiving box, ending the automatic cleaning of the material.
