Description

Technical Field

[0001] This utility model relates to the field of cigarette processing technology, and in particular to a cleaning device. Background Technology

[0002] The hemp fiber removal machine is one of the main pieces of equipment on the tobacco processing production line. It is mainly used to remove impurities such as jute ropes mixed in with loose, rehydrated tobacco leaves, so as to avoid the presence of foreign matter in the tobacco leaves and thus affect the product quality.

[0003] The hemp fiber roller is the main working component of the hemp fiber removal machine. After production, the densely arranged steel wires on the hemp fiber roller will be covered with a large amount of hemp fibers and other impurities. To ensure the normal function of the hemp fiber roller, it needs to be disassembled from the hemp fiber removal machine and cleaned periodically. In the existing technology, the hemp fiber roller is mainly cleaned manually using tools such as scrapers and brushes. However, due to the large surface area of ​​the hemp fiber roller, the large amount of debris, and the strong adhesion of the debris, the existing cleaning methods are difficult, time-consuming, labor-intensive, and inefficient. Utility Model Content

[0004] The purpose of this invention is to solve the technical problem of high difficulty and low efficiency in manually cleaning the entire hemp fiber roller using tools in the prior art. This invention provides a cleaning device that can clean the hemp fibers adhering to the surface of the hemp fiber roller, reducing the difficulty of cleaning and improving work efficiency.

[0005] To solve the above-mentioned technical problems, the present invention discloses a cleaning device for cleaning hemp fiber rollers. The cleaning device includes:

[0006] Mounting rack;

[0007] A sleeve extends along a first direction and is slidably connected to a mounting frame. The sleeve can be fitted over the hemp fiber roller and slide relative to the mounting frame along the first direction.

[0008] Cleaning blocks, there are multiple cleaning blocks, each cleaning block is located on the inner wall of the sleeve;

[0009] The drive mechanism is directly or indirectly connected to the sleeve. The drive mechanism is used to drive the sleeve to reciprocate along the first direction, and each cleaning block contacts the outer surface of the hemp fiber roller inserted into the sleeve.

[0010] By employing the above technical solution, the hemp fibers adhering to the hemp fiber roller can be scraped and carried to both ends of the roller and inside the sleeve, facilitating subsequent collection and cleaning by manual labor or equipment, eliminating the need for manual cleaning of the entire hemp fiber roller using tools. This device not only achieves a high degree of mechanization and automation in cleaning the hemp fiber roller, but also shortens cleaning time, improves cleaning efficiency, and reduces labor intensity.

[0011] Optionally, the cleaning block has a T-shaped cross-section, which is perpendicular to the first direction. The cleaning block includes a connecting part and a cleaning part. The connecting part extends radially along the sleeve. One end of the connecting part is connected to the inner wall of the sleeve, and the other end of the connecting part is connected to the cleaning part. The extending direction of the connecting part is perpendicular to the extending direction of the cleaning part.

[0012] By adopting the above technical solution, the T-shaped cleaning block allows the cleaning part to contact the hemp roller as an independent component. This not only increases the contact area between the cleaning block and the hemp roller, but also ensures that the cleaning surface of the cleaning block contacts the roller surface of the hemp roller evenly, thereby guaranteeing the cleaning effect.

[0013] Optionally, the inner wall of the sleeve is provided with a plurality of cleaning block groups spaced apart along the circumference of the sleeve, and each cleaning block group includes a plurality of cleaning blocks spaced apart along a first direction.

[0014] By adopting the above technical solution, the grouping and spacing of the cleaning blocks on the inner wall of the sleeve creates space for impurities, preventing hemp fibers and impurities from being squeezed between the cleaning blocks and the roller surface, thus affecting the subsequent cleaning effect. Furthermore, the design of multiple cleaning blocks spaced apart along the first direction ensures that the entire length of the hemp fiber roller is covered by the cleaning blocks during the cleaning process, resulting in better cleaning performance.

[0015] Optionally, it also includes a fixing rod, one end of which is fixedly connected to the wall, the fixing rod extends along the first direction, and the hemp fiber roller is sleeved on the fixing rod.

[0016] Optionally, a sliding mechanism is provided between the sleeve and the mounting bracket, the sliding mechanism including:

[0017] A slider is fixedly connected to a sleeve, and the slider has a through hole that extends through the slider in a first direction;

[0018] A guide rod extends along a first direction, passes through a through hole, and is connected to a mounting bracket.

[0019] Optionally, the slider is also provided with a threaded hole, and the drive mechanism includes:

[0020] A lead screw extends along a first direction and is rotatably mounted on a mounting bracket. The lead screw passes through a threaded hole and is threadedly connected to the threaded hole.

[0021] The motor, mounted on the mounting bracket, is used to drive the lead screw to rotate around its own axis.

[0022] By adopting the above technical solution, the cooperation between the drive mechanism and the sliding mechanism ensures that the slider and the sleeve fixed to it can only reciprocate along the first direction, avoiding deflection and tilting during the movement, thus improving the reliability and safety of the equipment.

[0023] Optionally, there are two sliders and two lead screws, and at least two guide rods. The two sliders are symmetrically arranged on both sides of the sleeve with respect to the axis of the sleeve. The two lead screws pass through the threaded holes on their corresponding sliders and are threadedly connected to the threaded holes. Each guide rod passes through the through hole on its corresponding slider.

[0024] By adopting the above technical solution, the sliding mechanism, which is symmetrically arranged with respect to the axis of the sleeve, can improve the stability of the sleeve during movement.

[0025] Optionally, a transmission mechanism is provided between the motor and the two lead screws, and the transmission components include:

[0026] Both first transmission wheels are mounted on the output shaft of the motor;

[0027] Two second drive wheels are respectively located at the ends of the two lead screws;

[0028] Two belts, one belt being fitted between a first drive pulley and a second drive pulley, and the other belt being fitted between another first drive pulley and another second drive pulley.

[0029] By adopting the above technical solution, the two lead screws are driven by two drive wheels on the same motor through independent belts, which can ensure that the rotation speed and direction of the two lead screws are consistent and highly synchronized, thereby ensuring that the sleeve can move smoothly and reciprocally in the first direction.

[0030] Optionally, the mounting bracket includes:

[0031] The base plate has a groove extending in a first direction, and the sleeve is at least partially disposed in the groove, and the sleeve can reciprocate in the groove in the first direction.

[0032] The first side plate and the second side plate both extend along the first direction. The first side plate and the second side plate are disposed opposite each other on both sides of the base plate along the second direction, which is perpendicular to the first direction. The first side plate is provided with two first mounting seats spaced apart along the first direction, and the second side plate is provided with two second mounting seats spaced apart along the first direction.

[0033] One lead screw has its two ends rotatably connected to two first mounting seats, and the other lead screw has its two ends rotatably connected to two second mounting seats.

[0034] Optionally, the mounting bracket is equipped with casters at the bottom.

[0035] By adopting the above technical solution, the rollers allow operators to easily push the entire mounting frame, which not only saves space and facilitates maintenance and repair, but also greatly improves operational flexibility. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0050] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0051] See Figure 2 , Figure 3 and Figure 5This utility model discloses a cleaning device for cleaning a hemp fiber roller 9. The cleaning device includes a mounting frame 1, a sleeve 2, a cleaning block 3, and a driving mechanism 4. The sleeve 2 is positioned along a first direction (e.g., ...). Figure 2 The sleeve 2 (shown in the X direction) extends and is slidably connected to the mounting frame 1. It can be fitted over the hemp fiber roller 9 and slides relative to the mounting frame 1 in the X direction. Multiple cleaning blocks 3 are present, each located on the inner wall of the sleeve 2. A drive mechanism 4 is directly or indirectly connected to the sleeve 2, and is used to drive the sleeve 2 to reciprocate in the X direction. See also... Figure 7 When the hemp fiber roller 9 is inserted into the sleeve 2, each cleaning block 3 comes into contact with the outer surface of the hemp fiber roller 9.

[0052] When cleaning the hemp fiber roller 9 is required, it is first inserted into the sleeve 2 along the X direction. Then, the drive mechanism 4 moves the sleeve 2 and the cleaning block 3 back and forth along the X direction. Since the cleaning block 3 remains in constant contact with the roller surface of the hemp fiber roller 9, it pulls and scrapes off the hemp fibers and other impurities entangled on the surface of the hemp fiber roller 9 during the movement of the sleeve 2. Some of the hemp fibers and impurities are pulled and scraped to both ends of the hemp fiber roller 9 by the cleaning block 3, while the remaining hemp fibers and impurities are scraped into the sleeve 2. The hemp fibers at both ends of the hemp fiber roller 9 and inside the sleeve 2 are then collected and cleaned manually or by a device.

[0053] By adopting the above technical solution, the cleaning device provided by this utility model can scrape the hemp fibers adhering to the hemp fiber roller 9 to both ends of the hemp fiber roller 9 and inside the sleeve 2, making it convenient for subsequent manual or mechanical collection and cleaning, eliminating the need for manual cleaning of the entire hemp fiber roller 9 using tools. This device not only achieves a high degree of mechanization and automation in cleaning the hemp fiber roller 9, but also shortens the cleaning time, improves cleaning efficiency, and reduces labor intensity.

[0054] Further, see Figure 5 Clean the cross-section of block 3 (e.g.) Figure 5 The cleaning block 3 (as shown) is T-shaped, with its cross-section perpendicular to the X-direction. The cleaning block 3 includes a connecting portion 31 and a cleaning portion 32. The connecting portion 31 extends radially along the sleeve 2, with one end connected to the inner wall of the sleeve 2 and the other end connected to the cleaning portion 32. The extending direction of the connecting portion 31 is perpendicular to the extending direction of the cleaning portion 32. The T-shaped design of the cleaning block 3 allows the cleaning portion 32 to contact the hemp roller 9 as an independent component. This not only increases the contact area between the cleaning block 3 and the hemp roller 9 but also ensures that the cleaning surface of the cleaning block 3 uniformly contacts the roller surface of the hemp roller 9, thereby guaranteeing a cleaning effect.

[0055] Further, see Figure 6The inner wall of the sleeve 2 is provided with a plurality of cleaning block groups spaced apart along the circumference of the sleeve 2. Each cleaning block group includes a plurality of cleaning blocks 3 spaced apart along the X direction. This application does not limit the number of cleaning blocks 3 and cleaning block groups. In one embodiment of this utility model, for example, there are 96 cleaning blocks 3 and 24 cleaning block groups, with each cleaning block group including 4 cleaning blocks 3. The grouping and spaced arrangement of the cleaning blocks 3 on the inner wall of the sleeve 2 can create a space for impurities. After the cleaning blocks 3 scrape hemp fibers and other impurities off the roller surface, these impurities can be pushed into or fall into the spaced spaces of the cleaning blocks 3, avoiding the impurities being squeezed between the cleaning blocks 3 and the roller surface, thereby affecting the subsequent cleaning effect. Furthermore, the design of multiple cleaning blocks spaced apart along the X direction can ensure that the entire length of the hemp fiber roller 9 can be covered by the cleaning blocks 3 during the cleaning process, resulting in a better cleaning effect.

[0056] Further, see Figure 1 and Figure 2 The cleaning device also includes a fixing rod 5, one end of which is fixedly connected to the wall 6. The fixing rod 5 extends along the X direction, and the hemp fiber roller 9 can be fitted onto the fixing rod 5. Rollers (not shown in the figure) are also provided at the bottom of the mounting frame 1. This invention does not specifically limit the number or installation position of the fixing rods 5; the number and installation position of the fixing rods 5 can be selected according to actual needs. When it is necessary to fit the cleaning device onto the hemp fiber roller 9 or remove it from it, the rollers allow the operator to easily push the entire mounting frame 1. This design eliminates the need for the cleaning device to be in a permanent working position. During use, the cleaning device is pushed near the fixing rod 5; after use, it is pushed away from the fixing rod 5. This not only saves space and facilitates maintenance and repair but also greatly improves operational flexibility.

[0057] Further, see Figure 2 The mounting bracket 1 includes a base plate 11, a first side plate 12, and a second side plate 13. The base plate 11 has a groove 111 extending in the X direction. The sleeve 2 is at least partially disposed within the groove 111 and is capable of reciprocating within the groove 111 in the X direction. Both the first side plate 12 and the second side plate 13 extend in the X direction, and the first side plate 12 and the second side plate 13 extend in a second direction (e.g., ...). Figure 2The groove 111 (shown in the Y direction) is arranged opposite to each other on both sides of the base plate 11, and the second direction is perpendicular to the first direction. A first end plate 14 is provided on the first side plate 12, and a second end plate 15 is provided on the second side plate 13. The first end plate 14 is perpendicular to both the first side plate 12 and the base plate 11, and the second end plate 15 is perpendicular to both the second side plate 13 and the base plate 11. Two first mounting seats 16 are provided on the first side plate 12 at intervals along the X direction, and two second mounting seats 17 are provided on the second side plate 13 at intervals along the X direction. One first mounting seat 16 is located on the first end plate 14, and one second mounting seat 17 is located on the second end plate 15. Exemplarily, the length of the groove 111 along the X direction is equal to the length of the hemp fiber roller 9 along the X direction, or the length of the groove 111 along the X direction is slightly longer than the length of the hemp fiber roller 9 along the X direction.

[0058] Specifically, see Figure 3 The drive mechanism 4 includes a lead screw 41 and a motor 42. A sliding mechanism 7 is also provided between the sleeve 2 and the mounting bracket 1. The sliding mechanism 7 includes a slider 71 and a guide rod 72.

[0059] Motor 42 is mounted on base plate 11 and drives lead screw 41 to rotate around its own axis. There are two sliders 71, symmetrically arranged on both sides of sleeve 2 with respect to its axis. See also... Figure 3 and Figure 4 The slider 71 is provided with a through hole 711 and a threaded hole 712 extending through the slider 71 in the X direction. For example, each slider 71 has two through holes 711 and one threaded hole 712.

[0060] There are four guide rods 72, all extending along the X direction. Each slider 71 has two through holes 711. Two guide rods 72 pass through the two through holes 711 of the same slider 71, and the other two guide rods 72 pass through the two through holes 711 of another slider 71. The two guide rods 72 located on the first side plate 12 are fixedly connected at both ends to the two first mounting seats 16, and the two guide rods 72 located on the second side plate 13 are fixedly connected at both ends to the two second mounting seats 17.

[0061] There are two lead screws 41, both extending in the X direction. The two lead screws 41 pass through the threaded holes 712 on their corresponding sliders 71 and are threadedly connected to the threaded holes 712. The two ends of the lead screw 41 located on the first side plate 12 are rotatably connected to the two first mounting seats 16, and the two ends of the lead screw 41 located on the second side plate 13 are rotatably connected to the two second mounting seats 17.

[0062] By adopting the above technical solution, the cooperation between the drive mechanism 4 and the sliding mechanism 7 ensures that the slider 71 and the sleeve 2 fixed to it can only reciprocate along the X direction, avoiding deflection and tilting during movement, thus improving the reliability and safety of the equipment. Furthermore, compared to a single sliding mechanism 7, the sliding mechanism 7, symmetrically arranged with respect to the axis of the sleeve 2, can also improve the stability of the sleeve 2 during movement.

[0063] Specifically, see Figure 3 A transmission assembly 8 is provided between the motor 42 and the two lead screws 41. The transmission assembly 8 includes two first transmission pulleys 81, two second transmission pulleys 82, and two belts 83. The two first transmission pulleys 81 are spaced apart along the X-direction on the output shaft of the motor 42, and the two second transmission pulleys 82 are respectively located at the ends of the two lead screws 41. One belt 83 is fitted between one first transmission pulley 81 and one second transmission pulley 82, and the other belt 83 is fitted between the other first transmission pulley 81 and the other second transmission pulley 82. The two lead screws 41 are driven by two drive pulleys on the same motor 42 through independent belts 83, which ensures that the rotational speed and direction of the two lead screws 41 are consistent, with high synchronization, thereby ensuring that the sleeve 2 can move smoothly and reciprocally along the X-direction. Furthermore, the cost of single-motor drive is lower.

[0064] During operation, the operator first places the hemp fiber roller 9, which has been removed from the hemp fiber removal machine, onto the nearest fixed rod 5. Then, the mounting bracket 1 is pushed to the vicinity of the hemp fiber roller 9 and pushed along the X direction towards the wall 6, so that the hemp fiber roller 9 enters the receiving cavity of the sleeve 2. At this time, each cleaning block 3 comes into contact with the circumferential surface of the hemp fiber roller 9.

[0065] The operator starts motor 42. Under the action of drive mechanism 4 and sliding mechanism 7, sleeve 2 moves back and forth in the X direction, driving cleaning block 3 inside sleeve 2 to move back and forth in the X direction as well. During this process, since cleaning block 3 can always be in contact with the roller surface of hemp roller 9, cleaning block 3 will pull and scrape off the hemp fibers and other impurities wrapped around the surface of hemp roller 9. Some hemp fibers and impurities are pulled and scraped to both ends of hemp roller 9 by cleaning block 3, and the other part of hemp fibers and impurities are scraped into sleeve 2. After all the impurities on the surface of hemp roller 9 have been scraped clean, motor 42 is turned off, the device stops working, and the operator pushes the mounting bracket 1 away from the wall in the X direction. The fixing rod 5 and hemp roller 9 are removed from sleeve 2. At this time, the operator can simply collect and clean the impurities inside sleeve 2 and at both ends of hemp roller 9, and then remove hemp roller 9 from fixing rod 5. The cleaning device provided by this utility model has a simple structure and can quickly clean and concentrate the hemp fibers and other impurities attached to the surface of the hemp fiber roller, thereby improving the work efficiency of operators, saving cleaning time, and reducing the difficulty of cleaning.

[0066] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
